Second To None is a mystery shopping company that I have worked with for a long time. They are one of my favorite companies for several reasons: jobs are available regularly, you are emailed jobs, but can also find them on the site, the schedulers are very nice (Hi Jason!), the review of your shop is always reasonable, and payment is like clockwork.
One of the agreements that you make when you contract with a company is confidentiality. This being the case, I cannot name the retailers involved. What I can tell you is that Second To None has contracted me for and offered me shops with banks, a popular sandwich restaurant, an office supply store, a coffee restaurant, and a health care company among others.
Second To None pays on the 15th of the month in the month following the one in which you completed the shop. If you did a shop January 2nd, you will be paid February 15th (or the first weekday following). All payments are made by Paypal.
This is an honest company that I have never had a problem with and have always enjoyed working for. I highly recommend them.
